A small selection of WW2 Canadian / German cartridges / casings for museum display

I am looking for several military cartridges or empty casings from WW2 to be used in a museum display. Specifically, we need up to 50 empty .303 casings that are preferably Canadian made and dated 1944 or earlier. We could use 10 Canadian made .45 casings dated 1944 or earlier and finally 10 German 7.92x57 (8mm Mauser) casings dated 1943 or earlier. Only empty casings are needed but if you have live rounds we have the ability to make them empty I am in the Edmonton area so any live rounds should preferably be located locally. Only military cartridges / casings please.
